Emissions from trucks

For a bright futureThe environmental impact of a truck is mainly generated from exhaust emissions. That is why we go all the way when it comes to research and development in cutting emissions and in staying at the forefront of environmental technology.

Efficient exhaust after-treatmentDiesel engines are highly energy-efficient. During the combustion process the temperature level is high and the cylinders are fed with a surplus of air to make sure that combustion is as complete as possible. Hydrocarbon and carbon monoxide levels are low compared with petrol ("Otto") engines.

On the other hand diesel engines produce more nitrogen oxides and particles than Otto engines do. By monitoring combustion, the balance between hydrocarbons/carbon monoxide and nitrogen oxides is regulated.

Fuel qualityDiesel fuel has a higher energy value than petrol does, but it also contains higher levels of sulphur and aromatic hydrocarbons. Currently, low-sulphur fuel can be found in countries such as Sweden, Finland and the United Kingdom.
